PiFast
A good indicator of CPU/Motherboard performance is version 4.2, by Xavier Gourdon. We used a computation of 10000000 digits of Pi, Chudnovsky method, 1024 K FFT, and no disk memory. Note that lower scores are better, and times are in seconds.
Pentium 4 @ 12x200

As with the synthetic tests, the ProSeries holds down the fort. The HyperX does well though, edging out the OCZ EL Gold.
Pentium 4 @ 12x250

The improved timings of the ProSeries is too much for the other two, but the HyperX still does quite well at 250FSB. At 2.6v, it also runs a bit cooler... at least according to the ole finger test.
Pentium 4 @ Maximum OC (HyperX @ 270FSB)

The clock speed deficit catches the HyperX again, but the affect isn't as much as in the synthetic tests.
TMPGEnc MPEG Encoding
Video editing is a taxing chore, and we'll be testing the HyperX using TMPGEnc 2.512 to encode a 7.78MB, 1:30 movie trailer to a 24FPS MPG file. Note that lower scores are better. All memory timings are at 2-3-3-5 at 200FSB.
Pentium 4 @ 12x200

Pentium 4 @ 12x250

Pentium 4 @ Maximum OC (HyperX @ 270FSB)

Dead even at 200 and 250FSB, and a one second victory by Corsair at the maximum OC settings. As soon as I find a suitable MPG that isn't pr0n, I'll update this test with a larger video file.
